Abstract: Method for controlling a dynamic linear motor. Method includes defining a path over which a rotor is to travel, placing stator segments at least along portions of the path where the rotor may be one of accelerated and decelerated and supplying a variable amplitude and frequency of voltage to power the stator segments in a synchronized manner so that, as the rotor approaches stator segments, the stator segments are powered and, as the rotor departs stator segments, the stator segments are depowered.

Abstract: A dynamic linear motor is controlled by determining a relative proximity of a moving rotor of the linear motor to a fixed stator segment of the linear motor using a current location of the moving rotor. A current driving characteristic of the linear motor at the current location of the moving rotor is determined. Settings for the fixed stator segment when the moving rotor reaches the fixed stator segment are identified based on the current driving characteristic. The fixed stator segment is driven based on the settings when the moving rotor reaches the fixed stator segment.

Abstract: A motor drive system for a linear motor having a plurality of stator segments and a rotor movable relative to the plurality of stator segments. The motor drive system includes a variable frequency drive comprising at least one energy cell, the variable frequency drive supplying a medium voltage between 1 kV and 100 kV and a plurality of switches operable to connect the variable frequency drive to selected segments of the plurality of stator segments based upon a position of the rotor. The variable frequency drive is connectable to an external energy source to at least one of charge the at least one energy cell or to supply power to the external energy source.
